﻿***Heat and temperature are related to each other, but are different concepts.
Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance. Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object. Temperature does not depend on the size or type of object. For example, the temperature of a small cup of water might be the same as...

Investigation Into Temperature Sensors
Introduction
In this project I will be investigating how it is possible to use a temperature sensor to keep a greenhouse from changing temperature too much. This is intended to help plants live and grow in their optimum temperature. This will create a perfect temperature for the enzymes in the plants to work in, and therefore resulting in a maximum growth/production rate. This could be useful for gardeners who wish to grow plants as quickly as...

Looking for a Gas
Gas is everywhere. There is something called the atmosphere. That's a big layer of gas that surrounds the Earth. Gases are random groups of atoms. In solids, atoms and molecules are compact and close together. Liquids have atoms that are spread out a little more. Gases are really spread out and the atoms and molecules are full of energy. They are bouncing around constantly.
Gases can fill a container of any size or shape. It doesn't even matter how big the container is....

Kinetic theory of matter explains that the same is compose of tiny pieces of, atoms or molecules in continues motion. The theory states...

Temperature and Thermometers
The Temperature of an object is a measure of the hotness or coldness of that object.
An alternative way to think of temperature is to say that “the temperature of an object is a number – on some manmade scale – that indicates the hotness of the object”.
‘Hotness’ in turn is a measure of the kinetic energy of the molecules of the material.
Note: You must use the term ‘hotness’.*
The SI unit of temperature is the Kelvin (K)*

Heat and Temperature
Heat is often described by the average individual as being the change in temperature from hot to cold. “Often the concepts of heat and temperature are thought to be the same, but they are not.” Heat and Temperature, para. 2) Perhaps the reasoning behind the incorrect reasoning is that humans associate the two together because when heat is applied to an object the temperature rises. The kinetic theory of matter better explains the underlying cause as to what takes...

Temperature Affecting Enzyme Activity
Introduction
The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life's processes would not come so easily. Enzymes are basically proteins, which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape, which makes enzymes different from other proteins. A common enzyme that we have is catalase, which breaks down...

Elodea has expanded all over the world as well, particularly in Europe. This aquatic plant multiplies rapidly and grows in a variety of conditions and environments, which is why it’s considered a weed. Elodea is often used in aquariums to stabilize the oxygen balance. It’s a fierce photosynthetic which...

The environments of Earth include conditions in which physical and chemical extremes make it very difficult for organisms to survive. Conditions that can destroy living cells and biomolecules include high and low temperatures; low amounts of oxygen and water; and high levels of salinity, acidity, alkalinity, and radiation.

Background:
The solubility of most solid substances is generally said to increase as the temperature of the solvent increases. However, some substances, such as ytterbium sulfate, do the opposite. This can be explained through the Second Law of Thermodynamics which states that “in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial...

Temperature is one of the weather elements and measures the degree of hotness and coldness in a place. The temperature of a place is affected by a number of factors such as latitudinal location, seasonal variations, albedo of the place, contrasts between land and sea and elevation. Latitudinal location has the strongest influence on the climatic conditions on a macro/global scale. The rest of the factors then serves to modify these influences and are secondary, operating at a smaller scale....

When external temperatures are cold, the body uses certain techniques to warm itself up. Likewise, as heat levels rise...

The Effect of Temperature on the plot in One Day in the Life of Ivan and The Strangers
One Day in the Life of Ivan by Dos. was a very successful book with many literary devices. The story is told in fist person at times and in third person in other. Dos. has incorporated many literary devices into this book. The Strangers was written during the 1950s by Albert Camus. The diction in this book is very high with many telegraphic sentences. Both authors use many symbols and motifs in there book....

﻿Lab #5: Dissolved Oxygen Lab
Be sure to read and understand the below instructions BEFORE the lab!
Experiment 1: Investigating the Effect of Temperature and Salinity on the Concentration of Dissolved Oxygen in Water
Introduction:
In an aquatic environment, oxygen must be in a solution in a free state (O2) before it is available for use by organisms (bio-available). Its concentration and distribution in the aquatic environment are directly dependent on chemical and physical factors and...

The simulation and analysis of liquid droplets with respect to heat capacity and droplet size
Abstract
Define
Using Molecular dynamic simulation a cluster of particles was modelled and their behaviour analysed with respect to temperature change. As proof of a specific state i.e. solid, the Mean squared displacement was calculated and illustrated with respect to time. This occurred for varying temperatures. From the internal energy of the system per time step, the heat capacity was...

How Does Temperature affect the Ability to Bounce
of a Ping-Pong ball?
Physics Design Practical
Research Question
How is the bounce-height of a ping pong ball affected by it’s temperature?
This research questions aims to find out how the temperature of a ping pong ball affects the vertical height bounce, after being dropped from 1 metre. I will be measuring the bounce height using a video camera to find the heightest point. I will use the top of the ball for ease of results....

Aim: Investigate the effect of different temperatures and chemicals including various pH levels, alcohol and detergent on the cell membrane structure as well as function.
Hypothesis: Increasing the temperature and pH levels which the beetroot membrane cells are exposed to will increase the amount of dye that passes out of the membrane.
Materials: Part A
• Bunsen Burner, Tripod and a Wire Gauze
• 250mL Beaker
• A 100° thermometer
• Matches
• 10mL measuring cylinder
• Sticky labels and a...

Naomi Ward
unit 5 P5- Explain the concept homeostasis with reference to the control of heart rate, breathing rate, body temperature and blood glucose.
In this assignment I will be introducing a formal report that is based on an investigation into how the body responds to exercise and which analyses the results from the investigation. The investigation involves myself and other pupils in my class. I will be doing the Harvard step test. the other pupils in my class will be monitoring my heart...

Introduction:
Biology is the science of life and thus one of the many sciences that are part of everyday life. Diffusion and osmosis are processes that are a constant in our lives, even though many don’t realize it. Medicaments such as Fervex can be drunk only after diffusion has taken place and the powder granules have diffused into the hot cup of water. On the other hand, every day we become unintentional witnesses of osmosis when the roots of the plants try to suck up the water from the...

Science Behind the Galileo Thermometer
The Galileo thermometer, used to measure temperature, is mainly used for home décor nowadays. The stylish thermometer used in people’s homes today is based off of a thermo scope Galileo invented in the early 1600’s. Although not exact, the Galileo thermometer is moderately accurate. The thermometer has several glass blown bubbles, with a colored liquid inside which is just for decoration. The bubbles have metal tags attached to the bottom of them with an...
